Application filed February 2. 1914. Serial No. 820,615.

To all 'w/l one it may concern:

Be it known that 1, WILLIAM P. QUEN- TELL, a citizen of the UnitedStates of America, and a resident of Montclai'r, Essex county, and Stateof New Jersey, have invented certain new and useful Improvements inCalculating-Machines, of which the following is a specification,reference being had to the accompanying drawings, forming a part tl1ereof.-'"

My invention, relates to calculating machines, and has special referenceto machines of the no'key-board type which are designed to add,register, and record numbers; to indicate the total-ofiall the numbersregistered in the machineand-to record the total as a footing to theitems previously recorded.

One object of my invention is to provide a machine of the aforesaidcharacter which shall be simple andrelatively inexpensive inconstruction and accurate and positivein operation.

Another object is toprovide simple and I particularly advantageous indexmembers of the registering mechanism.

and adding members, and means for governing the movement and determiningthe pended claims.

In the drawings: Figure 1 is an end clevation, with the casing brokenaway and shown in section, of a calculating machine embodyingmyinvention. Fig. 2 is a view corresponding to Fig. 1 except that the operating member is broken away to show the in dex segments and otherinterior parts of the machine. Fig. 3 is a plan view of the same machinewiththe cover broken away, to show the type hammers'as well as the partsFig. 4 is a from view of the machine with the cover broken away. Figs. 5and 6 are sectional elevations looking from the rear of the machine andtaken respectively on the lines 55 and 0-6 of Fig. 2. .Fig. 7 is adetail view of one of the actuating segments 'looking from the lefthandend of the machine and illustrating theme'thod of releasing the lockwhich holds the segment in position to record a desired item. The upperportion of'the samesegment is shown in Fig. 8 with the lock latched inits retracted position. Fig. .9 is a detail View of the totalizer memherand its attached parts. Figs. 10 and 11 are sectional views takenrespectively on the lines 10-10 of Fig. land 1l1 l of Fig. 2.

A slightly modified form of my invention is shown in Fig.12 which is aperspective detail of a portion of an index segment.

The'mach'ine illustrated in Figs. 1 to 11 inclusive of the drawingscomprises in general, a casing, an operating member 21, a totalizermember 11, a horizontal shaft 55,

lindex segments 57, 57", etc., adding wheel actuating segmentsfi 63etc.,' spacers 77,

:an oscillating frame 83 supporting adding Iwheel's'lSO and a carryingmechanism, type carriers 68, type hammers 137, a shutter 114, and areset mechanism for the shutter and type hammers. Each of the foregoingwill now be described in a separate section. 0aaz'12.g.'lhe casingcomprises a base 15 -(Fig, 4) having end brackets-wand 17 securedthereto and extending upwardly therefrom and a cover 18 which ispreferably formed of pressed steel, and has an open front exposing theindex segments and aperjtures 20 through which are exhibited the totalsindicated on the adding wheels.

Operating members-The operating member 21 (see Figs. 1 and 3) controlsthe resetting of the carrying mechanism, the moving of the adding Wheelsinto and out of mesh with the adding wheel actuatin segments, themechanism. for preventing tie printing of the type to the left of thehighest column registered, the printing hammers and the adding wheelactuating segments. It has a hub 22 which extends outwardly through abearing 23 in the end bracket 17 and thus provides a rotatable mountingfor the mem-- her. The hub also extends through the end wall of thecover-18 and has secured to its outer end an operating handle lever 24.The

body of the member 21 is flat and .is shaped to form an arm 25 and asegment 26 which terminates in a cam edge surface 27. Piv-.otally'secured to the member at one end of the segment 26 is a pawl 28,held against a" pin stop 29 by a spring 30; and adjacent to the camsurface 27 are a 'pair of similar.

pawls 3.4 and 35 which are likewise held against stops 36 and .37 bysprings 38. and

'39. The arm 25 supports a transverse bail 40 which is suitablysupported at its oppo site end by a radial arm 40 mounted to retate onthe shaft 55.

Totah'zer member.-The totalizer member 41 (see Figs. 3, 5 and 9)controls the mechanism for printing the total of the items added and itresembles the operatin memher, but is located at the opposite en of themachine. It has a-hollow hub 42 extending through asupporting bearing 43in. the bracket 16 and through the end of the cover, a handle lever 44being secured to its outer end. The member 41 has three radial arms '45,46, and 47; the arm 47 being T-shaped and provided with spring-pressedpawls 48, 49, 50 and 51 which correspond to the pawls 28, 31, 34 and 35of the operating member The arm 47 has a cam edge surface 52corresponding to the surface 27 of the operating member. The arm 45supports a'bale 53 which corresponds to the bail 40 of the member 21 andis supported at one end by an arm 58* mounted on the hub 22. A pin 54projects laterally from the end of the arm 46.

Horizontal shaft.The horizontal shaft 55 as clearly shown in Fig. 5,.issupported indirectly by the bearings 23 and 43, its ends being fittedfreely into the hubs 22 and 42 and constituting inside bearings for themembers 21 and 41. It also constitutes a bearing for each of the addingwheel actuating segments and the index segments. Pins 56 prevent alongitudinal movement of the shaft and thushold it in place.

Index segme'n ts.The index segments 57 57", 57 and 57 are similar andare uniformly spaced on the shaft 55. They limit the movement of theadding wheel actuating segments to correspond with the value of thenumber to be added and recorded, the latch carried on the actuatingsegment being locked into the selected aperture of the index member.Each of them comprises a hub 58, a radial arm 59 and a cylindricalcurved flange 6O in' which are a series of apertures 61 numbered 1, 2,etc., as shown in Figs. 3 and .4. Each segment has a s 'iring 62 whichtends to holdit in an elevated position against a stationary shaft 163or other suitable stop as hereinafter explained.

zlctuating scgmentsw The adding wheel actuating segments 63, 63", etc.,(see Figs.'

and 7) are alike except that the segment (33 is not provided with asmany attaclr ments because there is no index segment with which itcoiiperates, while the others respectively cooperate with the indexsegments 57",. 57, etc, Eachactuating segment has a. toot-hed periphery64,adapted to mesh with the teeth of the adding wheels as explainedbelow, a radial arm 65, a hub 66, and a type arm 67. Oneof the typecarriers (38 is ivotall secured to and do ends P t P from the outer endof each of the arms 67. As clearly shown in Fig. 6 these arms are offsetto throw the type carriers, which are near therear of the machine, closetogether and to give them a suitable spacing. A

spring 69 is secured to the radial arm'65 bya screw 70 and extendsbeyond the'edge of the arm in a substantially radial line. Its

outer end is in engagement with a stop 71 v Pivoted near the upper endofthe segment is a locking pawl 72 which is normallyheld in its retractedposition by the engagement of a latch 73 with a pin 72?, a single spring74 tending both to move the lock outwardly into the position shown inFig. 7 and to hold the latch in its locked position. A spring 75 tendsto move each segment in a direction oposite to the arrow 76 of Fig. 2.Each of the locks 72 has an offset branch 72 which engages the aperture61 while its end is rounded and extends beyond the surface of the indexsegments. to cooperate with the cam surfaces 113 Near the lower ends ofthe index e segments and extending transversely of the machine, is ashaft 103 to which is secured a plurality of latches 104. Each latch hasa releasing arm 105 which is adapted to be actuated by a lateral pinprojection 106 with which each of the index segments is provided. Eachof the latches 104 is normally held in engagement with a notch 107 inone of the actuating segments 63. All of the latches may be concurrentlyreleased by means of a bell crank releasing lever 108 which is adaptedto actuate a transverse bail 109. The repeater, as

clearly shown in Figs. 1, 2 and 4, comprises a pair of lever arms 111which are secured to a pivot pin 112 and are-interconnected by atransverse rod 113. One of the levers.

111 has an outwardly extending key which may be pressed down by thefinger of the operator for multiplying any number which has been set upas explained below. The actuating segments are moved while out of meshwith the adding wheels, to predetermined positions on the index membersof the same columns and are then locked by the engagement of theirlatches with the openings ofthe index members. Then the adding wheelsare brought into mesh with the actuating segments and moved by thelatter, the distance corresponding to the value of the number selectedon the index members.

Spacers-As clearly shown in Fig. 5, the adding wheel actuating segmentsand the index segments, with which they respectively cooperate, arerotatively mounted on the shaft 55 in adjacent groups. Their relativepositions are maintained by spacers 77 (see Figs. 1, 4 and 5). Thespacers are Similar to each other and each comprises a foot 7 8 which isbent at l 'ightangles to the body,

rests upon the base 15, and determines the distance between the spacers.Part of each spacer is formed into an are 79 which is adj aoent to thesegment 57 and has its center of. curvature coincident with the axis ofthe shaft 55. A latch 79 is pivotally mounted at the upper end of eachof the spacer arcs 7 9 in any suitable manner as, for example, one pivotshaft 79 Each spacer is also provided with a central hub 80 which isinterposed between the hubs of an index segment 57 and an adding wheelactuating segment 63. The hub 80 of the spacer is provided with hubprojections 81 and 82 which are formed integral with the central hub 80and are respectively folded over the aforesaid adjacent hubs. Thearrangement of parts is such that the overlapping hubs of the spacerhold the other segments in position without interfering with the limitedrotative movement of each segment, which is all that is required foroperating the machine. The latches 79 are arranged to be concurrentlyreleased by a releasing bail 160 which is carried at the outer end of apair of spaced arms 161 and 162, and is arranged to be swung about ashaft 163 as a-pivot. The bail 160 is actuated to release the latches'79 by a spring 164. It is curved into a retracted position and normallheld in this position as shown in Fig. 2, by the bail 10 which acts upona cam extension 165 of the arm 161. 1

. Oscillating frame-The oscillating frame 83 (see Fig. 1) carries theadding wheels and comprises a pair of end rockers 84 which are pivotallymounted on a stationary transverse shaft 85 and are located near therespective ends of the machine;-a shaft 86 on which the adding Wheelsare rotatively mounted, and a plurality of shafts 87, 88,,

89 andv 90. Each of the adding wheels 180 comprises a toothed gear wheel181, an index drum 182 numbered 0, 1, 2, etc., and a pin 183 which isadapted to actuate the carrying mechanism. A. stationary shaft 91servesas a stop against. which the frame is held by a spring 92 exceptwhen the adding wheels are thro- 711 into mesh with their actuatingsegments. A stationary shaft 93 is arranged to engage'a tooth slot ofeach of the adding wheels when the frame is against the stop 91, for thepurpose of preventing the wheels from being turned whenin this position.

Carrying mccham'sm.The carrying mechanism for carrying the decimal fromthe lower to the higher column atthe complete rotation of the addingwheel of the lower I column, is as follows: Pivotally mounted on theshaft 87 are a plurality of stop levers 94, each of which'is held in'ltS retracted position by a latch 95, asingle-s ring 96 tending to holdthe latch in its loot-zed p p iilatches 95 are pivotally mounted ',onthe shaft 88 and each is adapted to be tripped as here higher column. Alatch 99 is arranged to hold the frame 83 so that'the adding wheels meshwith the teeth of the actuating segments, when once it has been adjustedto' this position.

Reset frame-The reset frame is for resetting the carrying mechanism tooperative position after having carried. It also moves theadding wheelcarrying frame into position to engage the wheels with their actuatingsegments. The shafts 89 and 90 form parts of a reset frame (see Fig. 2)comprising levers 100 which are pivoted on the shaft near opposite endsof the machine and are oined at corresponding ends by the shafts. Theshaft extends above projections 84* of the end rockers 84: and the shaft89 extends through slots 101 therein. The parts are so arranged that thereset frame when actuated, notonly swings the oscillating frame 83 as awhole, upon its pivot 85, but also by reason of the engagement of theshaft 89 with projections 102 resets such stop levers as have beentripped.

Type caWiem.-The type carriers 68 which are in the form ofcircumferentially curved strips mounted on edge, are guided by a seriesof annular grooves 124 in a guide shaft 125. This shaft is substantiallyparallel to the shaft 55 and is supported in the back central portion ofthe machine by stationary spaced lugs 126 which are parts of a pair ofstationary uprights 126. The type carriers are beyond the shaft and eachof 'them has secured to its outer edge a series of suitable type 68 (seeFigs. 2 and 6). The cover 18 is broken away at 127 opposite to the zerotype when the machine occupies its zero position. Below this point thecasing is extended backwardly to make room for the hammers and theactuating mechanism therefor. Beyond this casing extension, suppOrted bythe bracket 128, is a paper roll 129, a strip of paper being led fromthe roll under guide rolls 130 and 131, through a pair of feed rolls132, over guide roll 133, and upwardly passed the opening 127 in thebody of the cover. The feed rolls for the paper are actuated in theusual manner by a pawl and ratchet 159 which mechanism is operativelyconnected to the arm 144 by a link 159. Above the casing extension onvertical shafts 172, is .a pair of ribbon rolls 13e,135, a ribbon 136extending-from one roll to the other between the strip of.

pa 7.2 and the opening 127.

- hamme -The. type hammers Y 137.

are mounted on a pivot shaft 138. which is substantially parallel to theshaft; 55. They are spaced apart as is clearly shown in Fig.

3, to correspond to the spacing of the type carriers and each of them isin the plane of the carrier to which it corresponds. The hammersare-actuated by a bail 140 which is supported by; levers 141, and 142and against which the hammers rest as shown in Figs. 2 and 11. Thelevers are secured to a pivot 143 and the lever 142 has an extension 144whichmay be engaged by a latch 145. A! spring 146 tends to move the bail140 so as to actuate the hammers and consequently the hammers areactuated whenever the latch 145 is" .released This latch extendsupwardly as shown in Figs. 1 and 2 35 of the member 21. I Ashereinafter'explained it may also be tripped by the pawl 51 of themember41, the latch being socured to a pivot shaft 147, and a correspondinglylocated arm 145 being found at the opposite end of the machine. The bail140 extends through slots 148 inthe partition walls of the casingextension, the arrangement being such that the hammers are not carriedall the way but are merely actuated by the bail, their momentum beingsufiicient to carry their striking ends against the strip of paperwhich, together with the ribbon 136, is carried against the the paper ina Well known manner.

Shutter.-The shutter114 (see Fig. 6)

which prevents the printing of the type to the left of the highestcolumn to be printed is in "the form of a bell crank lever and ispivoted at 115 on a stationary bracket 116. It is located near the'back' of the machine and is mounted to swing in a vertical plane whichis substantially parallel to the shaft 55. tending circumferentiallyfrom the outer end of one of the arms ofthe shutter is a.

' pair-of parallel fingers 117, 118,'thefinger ll8zbeing offset as shownin Fig. 2. The extremityof the other arm is considerably offset forming"a section 119 at right angles.

to the body of the shutter. A projection 120 at right angles to thesection 119 is adapted to be engaged by a. latch 121 which holds theshutter .in a retracted position in opposition to aspring 122. The latch121 is retracted by a spring 122 and has an extension 122 and isarranged to be released as hereafter explained, by the pawl'34 of themember 21.. In fact, the latch is secured to a pivot pin 123, near theopposite end of which, is an arm 121* which is arranged to be actuatedby the pawl 50 of the totalizer xmember-41. The striker on the end ofthe hammer is bifurcated asfshown in Fig. '2,

in r113 finger 117 of the shutter moves through predetermined.conditions as explained below. Only those hammers which are not stoppedby the shutter are active'in print Attention is directed to the factthat a guide notch 150 and crosses the path of movement of the typecarriers. If the typc carriers are set to print zero,-they-. do notextend into the path of the shutter but otherwise theydo,andconsequently the motion of the shutter in each case is determined bythe 'highest digit of which t-he number, set up in the machine, iscomprised. As explained below this prevents the printing. of zeros aheadof the number set up.

Reset for shutter hamnncra-The reset for the shutter and for the hammerscom and is adapted to'be actuated by the pawl prises a bell crank lever151 secured to one end of a pivot pin 152 and provided with a roller 153which cooperates with the cam surface 27 of the member 21. At theopposite end of the pin 152 is aflixcd an arm 154 having'a roller 155-which cooperates with the cam surface 52 of the member 41. The

1 lower arm of the bell crank lever 151 is pro- 5 vided with laterallyiprojecting'pins 156 and 157 which respectively cooperate in resetting,

with the arms 119 and 144. The reset lever 151 may be retracted by aspring 15 On the shaft of one of the paper rolls is a worm gear 170which meshes with a gear wheel I 171 mounted on the ribbon roll shaft172. type, the, imprint'of the type being left on The operation of myinvention is as fol- 'lows:-assuming that it is first desired to .set upthenumber 78 in the machine, a

pencilorstylusis inserted in the aperture 61 of the index segment 57which is numbered 8, this segment corresponding to the units column.

A slight downward movement is imparted by the stylus to the segment.This movement is limited by the latch 79 as clearly shown in Fig. 2. Asa result of this movement the pin 100 acts upon the arm 105 and releasesthe latch 104 from the notch 107 of the actuating segment 63. thenreleased this segment is immediately moved upwardly by its spring untilasshown in Fig. 7, the latch 73 comes into engagement with the pencil orstylus and releases the lock 72, permitting its exthen pulls down on theactuating handle lever 24 and as a result a rotative movement is"imparted to the actuating member ,21.

The net-121s, first tripped by the pawl 34 :and shortly afterward thelatch 145 is tripped bythe -pawl 'and the pawl 31 acts as a cam,pressing down the shaft 90 and thereby causing an oscillation of theadding wheel frame The spring 122produces a rotative movement of theshutter 114 as soon as the latch121 is released. The movement of theshutter is 'arrested by the first depressed type *carrier which is inthe path of the finger 117. In the example assumed this is the typecarrier68 which corresponds to the. tens column. The finger 118' isslightly shorter than the finger 117 but long enough: to arrest'the typehammers corresponding'to the hundreds and other higher columns;- Thereleasing of the latch-145,

after the setting .of the shutter, releases the bail 140T which, reasonof the'action of fthe spring 14'6 ;actuates the hammers 137.

' The numberf78 which was thus set up, is

ithusQ-printed on the strip of paper as $1 ready explained. furthermovement of the actuatingflmember 21 rocks the bell crank lever're'asonof the cotiperation between the "cam surface 27 and the roller153.. v The pins 156 and 157 carried by the lower arm'bf the bell cranklever 151,-engage the arms 119 and 144 and reset the shutter and thehammer bail. These parts are immediately latched in their reset posi- Ytions since the latches 121 and 145 are both spring 'pressed. Theoscillation of the frames?) produced as above indicated by theengagement of the pawl 31 and the shaft '90,

throws the adding Wheels into m'eshwith the actuating segments of thesame column there being an adding wheel and a segment for each column asalready explained,

It will of course be understood that the adding wheels are thrown intomesh with the segments while the segments are in the positions to whichthey have been set, the

tens and units segments being set at 78 1n. the' example assumed. Theadding wheels are locked in their engagingposition after explained. On astill further movement of the actuating member 21, the bail 40 comesinto contact with the springs 69, and moves the segments 63 and 63downwardly until they occupy the positions which they occupied atfirstasshown in Fig. 2 and in which-they are locked against upward move ment:by the latches 104. During the downward movement they actuate theadding wheels with which they coiiperate in a direction indicated by thearrow 76 By this means the adding wheels are rotated to register thenumbers previously set up. As

the actuating segment 63 of the units and tens columns move downwardly,they of course carrywith them the index segments 57 and 57 t6 which theyhave been attached by the locks 7 2. The index segments are released assoon as the locks 72 are forced inwardly by coming into contact with thecam surfaces 113 At the same time they are locked in theirretractedpositions by the latches 73 engaging the pins 72?. The, index segmentsare then immediately returned to their initial positions by the springs62. Near-the end of the downward stroke of the operating handle the pawl28 of the actuating member 21 rides over the upper end of the latch 99.The downward movement of the handle lever is now completedand the returnstroke is commenced. The first result of the upward movement of thehandle .is the tripping of the latch 99 by the pawl pinges on the cam165 and returns the bail 160 to its normal position as shown in Figs. 1and 2. The latches -79 are thus permitted to drop back into theapertures at the upper .end. of the index segments. By the operationthus described, the number 78 is printed on the paper strip and isregistered on the adding wheels.

In order'to explain the carrying mechanism it may be assumed that 6 isto be added inthe units coliunn. The operator proceeds as before and theoperation ofthe mechanism is the same except that as the adding wheel180 in the units column completes a full revolution "the pin 183 whichis carried by the wheel, trips the latch 95 and releases the stop lever94 permitting it to be moved by thespring 96 until thejarm 98 isdisplaced from its normal position a distance sufiicient to permit thesegment to register one more number. As. already explained, the arm 98isoffset to ooii'perate with the pin 71 of the segment of the nexthigher column. 7 i

When the bail 40 completes its downward movement it compresses thespring 69 of each of the actuating segments, each segment being held bythe engagement of its pin 71 with the arm 98 of the stop lever "of thenext lower column. Since in adding 6 to the units column the stop lever94 has been released from its norma'Lposition, it follows that thecompressed spring 69 of the tens column will force its segment downwarduntil'the pinis stopped by the arm 98 and this extra movement causes theregistering of one more number 6n the tens add- I I ing wheel. Thus thetotal will read 84.

with their actuating segments as explained above. The stop lever 94 isnot'r'eset until the next downward movement of the actuating lever 21.Then pawl 31, by reason of its engagement with the shaft 90, firstactuates the reset frame 100 which, as already explained, acts upon thearm .102 of the stop lever and returns it to its normal position, thefurther depression of the shaft 90 serving in the usual manner tooscillate the frame and to throw the adding wheels into mesh with theirsegments.

WVhen the machine is used for multiplying, the number to be multipliedis first set up on the machine as already explained. The operator thenpresses down on the key 110 so as to throw the cams 113 out of the pathof the locks 7 2*. Supposing the multiplier to be 3, the operator movesthe handle lever through three complete strokes, re

leasing the key 110 however, at the begin-' ning of the third stroke. Itis evident that when the key 110 is pressed the index segments and theactuating segments which have been set remain locked and consequently itis unnecessary for the operator to repeatedly set up the number by meansof a pencil or stylus, the index segment serving each time to limit theupward movement of the actuating segment, causing it to stop each timeat the number originally set up.

The feeding ofthe paper for each successive item is effected by aratchet and pawl 159 in a well known manner, this mechanism beingactuated by the hammer actuating bail to which it is connected by a link159; The

ribbon is also fed since it is operatively connected to the feedrollshaft on "which the ratchet is mounted. In order to print theitotal ofthesum added as a footing to the items jsuccessively printed .as aboveex plained,the operator ulls .down the totallzer handle lever i i. hemovement of the leverproduces a; downward movement of the totaliz'ermember 41 and as a first result,

the bail90fifs depressed by t e pawl 49 thereby resetting,z jsueh' ofthe s epie'v'ers 9 4 as havebeenreleased .inthe previous 0pera ion, andthrowing the addingjfiwheels into mesh with .the actuating;segmeiits.-"

Attention is dire'eteda'to m rina that the s'e ents" are all] in 1 theiriiorm'al position w entire-adding wheels.,ar,e brought into mesh. Thepin 54 jnext,engages the arm 108 thereby releasing allof the latches 104corres ondin 'l the t e carriers are in position. to print the numbersthat were on the adding wheels before they were returned to zero.Further movement of the totalize'r member 41 actuates the shutter andthe hammer mechanism in the same-wayas they were actuated by the member21, and causes the total to be printed on the paper. F urther movementof the totalizer member 41 causes pawl 48 to trip the latch 99, which isarranged to betripped in either direction,

. and the spring 92 immediately swings the oscillating frame 83 andwithdraws the adding wheels from mesh with the actuating gears.Attention is directed to the fact that the operation employed inprinting the total also clears the machine.

The index segments'may be modified as shown in Fig. 12 by making theapertures larger andpreferably open at one end, and arranging the latchto protrude beyond the face of the index segment so that it will strikethe operators finger.
